Re: City of Port Arthur
WWTP Improvements Project
Change Proposal—Debris Removal @ MOLS Wet Well
Dear Mr.Jones:
Allco proposes the following change order in the amount of$19,550.00 to remove and dispose of debris from the Main
Outfall Lift Station Wet Well:
DESCRIPTION/COST SUMMARY
Debris buildup in the wet well is causing issues with the pumps.It is recommended the debris be removed to ensure
proper operation.
The scope includes removal of debris with a vacuum truck and disposal.If larger debris is encountered it could make
removal difficult and pricing may need to be adjusted accordingly
Allco will load the debris into a dumpster and haul off to WWTP;if any special permitting or fees are required then
that will be an additional cost
Time Extension—TBD
ITEM LABOR MATERIALS EQUIPMENT SUBCONTRACTOR MARKUP/OH TOTAL
Debris Removal @ $9,750.00 $0.00 $7,250.00 $0.00 $2,550.00 $19,550.00
MOLS Wet Well
Please contact the undersigned if you have questions or issues regarding this matter.
Respectfully,
Allco, LLC

Good morning Scott-Brandon,
I spoke with Jeff this morning about what is needed at the City of Port Arthur WWTP.Jeff has spoken with your
onsight electrical tech about what you are needing in order to complete the installation.Jeff advised your tech that
a various relays need to be installed and wired up to your new system,as well as creating logic to make the
parameters that you are going to monitor function.The parts(relays)required are on Jeff's truck.We can get you
the part numbers once were on sight.I apologize for the simplistic overview but the easiest way for me to explain
what needs to be done.If approved,please sign and return our proposal as well as a payment method.I have
attached a credit card authorization form as well as a link to apply for an account with us in the event you choose
to do so as I am not sure whether you have an account with us.Do not hesitate to reach out to us if there are
questions or concerns,and I will be glad to assist.
Jeff,is available tomorrow and Friday if you are interested in getting him out there ASAP. Be advised that Jeff is on
vacation all next week per our scheduler.

Good Afternoon,
I was directed to reach out to you in regard to having some new Relays installed on this existing
Generator in Port Arthur.
They have already been in contact with Jeff and Gabe, but the GC just called me asking for someone to go
out to the field or hop on a call to get everything installed.
Are you able to help with this?The contact for the GC is below.

Just starting this email so we can coordinate together. It may be beneficial if we all got on a call to
discuss what we have in the field and what we know is missing. W-Industries can talk more

Update on engine not starting found that the fuel supply hose was cracked and dry rotted had to go and
get a new hose I also installed a check valve on the fuel supply.The hose being cracked made it lose its
prime and when it was trying to start it was sucking air into the fuel system, I primed the fuel system ran
the engine for 15 min and took the fuel psi reading from the engine ECU and everything looked good no
error codes on engine ECU please see the pictures

Aeration Basin-Seat Off Gate&Pump Down Basin
See drawing below for your reference. We will first need to build a berm on the backside of
the aeration basin to set up the long stick track hoe. Allco will then seal off the effluent
gate by installing a'h"steel plate w/2"foam board with our crane. We will then use the
long stick to install approximately 1,200 sandbags behind the steel plate to ensure the gate
is properly sealed off. Next,we will set up a 6"pump to remove the water in the basin. No
sludge or grit removal is included. At this time,we can perform an inspection of the
diffusers and air piping to determine scope of repairs. We will remove the sandbags, plate,
etc.at the City's direction.
Existing Slide Gate-Does the City want us to attempt repairs on the gate while the basin is
drained? Do we want to include a contingency amount to address the gate repairs or
replace if necessary? It is possible one of the ide gates not used at the Main Outfall could
be installed here. We will not know for ce in until we pump down the basin.
This proposal is for installation of the
bulkhead and preparation for
inspection of equipment in the
channel. Repairs will be included in a 10'
separate change proposal.
